The best restaurants serving Japanese food in Cardiff South Wales

If I could give this place less than one star, I absolutely would. Please learn how to respect customers.

Fantastic food with high quality ingredients and warm and friendly staff. Really amazing spot for a Japanese treat. Will be going back.

“Aquí anoche, y tengo que decir... que fue una comida. La comida no era mala, pero tampoco me daban ganas de escribir poesía al respecto. Si el sabor fuera una perilla de volumen, este lugar lo pondría en un educado 3. ¿Comestible? -Sí. ¿Memorable? Solo porque todavía estoy pensando en lo abrumador que fue. ¿Regresaría? Quizás... si mis papilas gustativas desarrollaran de repente problemas de compromiso”.

Great food, authentic, best japanese place in town hands down. Me and my wife are sushi lovers, and this place does it best.

don’t know why some people gave this place a low rating (when we checked on google). my girlfriend and i got greeted very nicely and was immediately made aware that there was no rice available as their rice cooker had broke, and they offered various substitutions for this problem. there were only two servers and it was quite busy when we came in. the seating was comfortable and the atmosphere was very homely and relaxed. we didn’t have to wait long, 10 minutes at least which was plenty of time for us to get settled in and decide what to eat. i ordered the prawn katsu curry (forgetting that there was no rice available) and when i asked for it the server made me aware that there was no rice left, however, if i so wished, i could get the rice cooked with no promise that will be cooked thoroughly and that it might be a little/very crunchy. i happily accepted those terms as i am a fan of crunchy rice. my girlfriend ordered the tonkotsu ramen with pork. we got our food delivered within a reasonable amount of time and the portion sizes took us by complete surprise. they were a lot bigger than we expected, but they were perfect portions as after finishing i was neither too full to the point i was uncomfortable, nor was i still hungry for anything else. the prawn katsu curry was DELICIOUS!!! our server had warned us that the rice may not turn out good due to the rice cooker malfunctioning, however, the rice was perfect. my girlfriend adored the ramen as it was creamy and well prepared, it would melt in your mouth perfectly. unfortunately they didn’t have desert available, but that didn’t ruin the food that we had just eaten. once again the servers the extremely friendly and welcoming, giving us recommendations when we asked, apologising for any problems even though they didn’t have to, overall it was just amazing. highly recommend this place if you’re a fan of japanese food. will definitely be coming back here on my next trip to cardiff!

This is my new favourite restaurant. Cozy, unassuming, family run with a warm and welcoming atmosphere... and then the food arrives. There was silence at our table except for the occasional sigh as we enjoyed a taste sensation. I can only say you must pay Osaka in Cardiff a visit. You won't regret it.

Consistently shocking service. I feel like the person who works there has a future as a doctor's surgery receptionist, they do as much as possible to prevent you ordering. They try and get you to use a machine to order, which often doesn't work, and if you mention it you get scowled at. They seem unaware of how to fix it. They are extremely rude when you arrive and if you're lucky enough to get their attention they treat you as an inconvenience, manners don't exist. They are obviously focused on Deliveroo rather than walk ins for lunch. Sadly it's nice enough sushi (albeit a very confusing menu that makes no sense on the ordering machine) but the service is rude and confusing. This has happened on too many occasions now and I won't be returning.

Esta fue una experiencia increíble, te sentabas y te daban un menú. En la mesa tienes salsa de soja y una servilleta, plato y palillos sin embargo puedes conseguir cubiertos si lo pides. Cada plato de sushi y otras comidas fueron hechas a mano y servidas más o menos inmediatamente. Luego, junto a los asientos está la cocina donde se puede ver la comida que se está haciendo, que es genial para ver! El personal era muy agradable y pude encajonar cualquier comida que no podía terminar. Cada plato se coloca en una cinta transportadora y lentamente vienen alrededor y simplemente puede recoger un plato, cada plato tiene un cierto color que corresponde con un precio en la parte delantera del menú. En el menú te decían los diferentes platos y si no te gustaba nada en el cinturón podías pedir una comida, pedí un pollo Katsu. Y estuvo delicioso hicieron el arroz más suave que creo que he probado en un restaurante y el pollo se cocinó tan bien : ) Fue un ambiente encantador y una gran experiencia en general, sin embargo, cuando llegó la factura nos preguntaron si teníamos algún descuento, por ejemplo, una tarjeta azul claro. Luego agregaron una propina de servicio que era bastante pesada, y probablemente podrían haber comprado otra comida. Esto me pareció bastante extraño ya que recogiste la comida tú mismo. Pero esta fue una gran experiencia y sin duda recomendaría a cualquiera que le guste el sushi! También puede hacer su pedido en línea y obtener servicio de puerta de Deliveroo, Uber Eats y Just Eat. ¡También puedes encontrar su menú en línea!

Been here twice in the last fortnight, fantastic menu, fantastic food, great atmosphere. Very reasonably priced and the quality is excellent. If I had to find fault I would say that the CS Ramen was a little bland but the array of condiments sorted that out. Highly recommended
